1. A radiotelephone comprising:
- a single radio frequency chain and a single baseband processor that is connected thereto,wherein the single radio frequency chain and the single baseband processor that is connected thereto are configured to communicate with both a space-based system and a terrestrial wireless network using frequencies of a satellite band;
wherein the single radio frequency chain and the single baseband processor that is connected thereto are further configured to communicate with both the space-based system and the terrestrial wireless network using substantially the same air interface; and
wherein the substantially the same air interface is a Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiplexed (OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Frequency Division Duplex (FDD) and/or Time Division Duplex (TDD) air interface.
